WAN a "CHAN/64L Alluring fir f orid-0m United States Patent 3,136,760 DOOR MORTISING TEMPLATE AND HOLDER Joseph W. .iuneinan, 5878 E. Hardwick, Lakewood, Calif. Filed July 2, 1962, Ser. No. 205,882 2 Claims. (Cl. 144-144.5)

The present invention relates generally to woodworking apparatus, and is more particularly concerned with a holder of simple construction arranged to interchangeably receive a multiplicity of templates for mortising door edges to selectively accommodate any desired one of a great variety of hinges and top pivots as fabricated by different manufacturers.

Heretofore, the mounting of offset floor hinge arms, center hung floor hinge arms and top pivots has presented a diflicult problem due to the existing, and often slight variations in the structures of the different manufacturers.

Due to this lack of standardization, time consuming and make-shift procedures have been followed which entailed the use of crudely constructed templates of plywood, Masonite and other materials which were nailed or temporarily secured to the door and used to guide the router tool.

Having the foregoing in mind, the present invention has for one object the provision 'of a mortising device of simple construction which may be quickly and easily attached to the workpiece, such as a door, this device having a frame structure adapted to interchangeably receive a pluralityof guiding templates representative of the hinge and pivot structures of the various manufacturers. In this manner, a relatively small number of templates may be utilized and take care of the majority of the manufacturers products, thus permitting accuracy of installation and saving of time.

Another object of the invention resides in the provision of a device of the character described which is so arranged that the router may be placed in a starting position in which the tool is out of engagement with the workpiece, and after starting may be laterally moved into working engagement with the tool operating at full cutting depth.

Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.

Referring to the accompanying drawings, which are for illustrative purposes only:

FIG. 1 is a perspective view of a mortising template and holder according to the present invention in aflixed position on a workpiece, such as a door;

FIG. 2 is a fragmentary plan view;

FIG. 3 is an elevational view as seen from one side, portions being cut away to more clearly show the fastening means for a template; and

FIG. 4 is an elevational view of the opposite side.

Referring generally to the drawings, for illustrative purposes, the template holder, as generally indicated at A, is shown as being affixed in its operative position upon a workpiece, in this case a door, as generally indicated at B.

Although various materials are readily available from which the template holder may be constructed, it is preferred to utilize a light strong material such as aluminum plates which are readily fabricated and in the finished product provide a lightweight device which may be easily transported for use in different locations.

The template holder A embodies a box-like frame structure in which a relatively heavy plate member and a somewhat thinner plate member 11 are secured by appropriate means in right angled relationship. As thus secured, the inner flat surfaces of the plates may be placed in engagement with the side face 12 and edge face 13 of the door so as to position the device in operative position thereon.

' cooperatively associated with the plates 10 and 11, is an end plate 14 which is positioned at a right angle to each of the plates 10 and 11 and has an inner surface adapted to engage an end edge face 15 of the door and thus cooperate in the positioning of the device in an operative position.

The frame structure thus formed is removably afiixed to the workpiece by the provision of C-clamps 16 and 17 respectively fixedly secured to the ends of the frame structure. These clamps are so oriented that the adjustable clamping pads 1818 thereof may be manipulated by the manually operable screws 19 in each case into engagement with the opposite side face of the door from the side face 12.

In order to mortise the door edge for offset hinge and pivot arms, the mortise recess must be substantially L- shaped with an end leg portion which extends into the side face of the door. In order to take care of templates having an L-shaped guiding slot therein, the plate 11 is provided with an L-shaped opening 20 which has an elongate leg portion 21 which extends lengthwise of the plate, and a short leg portion 22 which extends transversely towards one side of the plate.

For accommodating a template, as indicated in FIG. 1 by the numeral 23, the plate 11 is provided with a raised peripheral flange which includes side flanges 24 and 25 positioned on opposite sides of the opening 20, and end flange portions 26 and 27. The peripheral flange cooperates with the portions of plate 11 surrounding the opening'21 to provide a recess which is arranged to receive the template 23 fiatwise therein. The exposed surfaces of the peripheral flange lie in a plane which is parallel to the under surface of the plate 11, and provide a hearing face for the face-plate of a conventional router which will thus be movable to guide the router tool as dictated by the guiding opening in the template.

The illustrated template is shown as containing an L- shaped opening 23 which comprises an elongate leg portion 29 and short leg portion 30. A multiplicity of interchangeable templates may be used to provide the proper mortising for the various manufactured hinge arms, and the required guiding opening 28 is made of such dimensions as may be required. Of course, the opening 21 is made sufliciently large that it will not interefere with the opening of the template.

For retaining the template in the holder, a projecting pin 31 is provided in the end flange 27, this pin being arranged to extend into a recess 32 in the adjacent end of the template. At the opposite end, with the template in operative position, a thumb screw 33 may be actuated to enter a recess 34 in the adjacently disposed end of the template. Various templates are therefore easily positioned in the holder, and changes may be readily made from one template to another.

Referring to FIG. 2, it will be observed that the side of the plate 11 containing the flange 25 is mounted in overhanging relation with respect to the plane of plate 10. As thus arranged, the outer end of the short leg portion 22 of the opening 20 extends beyond the plate 10 and provides a space for receiving the router tool in a starting position in which the tool will be out of engagement with the adjacent door material. To begin the routing operation, the tool may then be moved from the starting position into engagement with the door material by laterally moving the router so as to pass the tool through a cutout 35 in the adjacent face of the plate 10. Thus the cutting tool may be started at its full cutting depth and proceeding the routing or mortising operation, being guided by the opening in the template 23.

Various modifications may suggest themselves to those skilled in the art without departing from the spirit of my invention, and, hence, I do not Wish to be restricted to the specific form shown or uses mentioned, except to the extent indicated in the appended claims.

I claim:

1. A mortising device, comprising:

(A) a frame structure adapted to be applied to the marginal edge portion of a door, including (a) a first plate and a second plate in right angled relation cooperating to position the frame structure in an operative position with the plates respectively engaging the edge face of the door and the adjacent side face of the door, one of said plates having an overhanging side margin extending outwardly of the plane of the other plate, and an opening having portions extending on opposite sides of said plane;

(B) marginal edge portions projecting from the outer surface of said one of said plates to form a template receiving recess, the outer surfaces of said edge por tions lying in a plane parallel to the plane of the door engaging inner surface of the plate for guiding engagement with a router face-plate;
